Steam purifier



April 19, 1932- w.' FRIEDRICH STEAM FURIFIER Filed Dec. 12, 1928 Fly/I ATTORNEY Patented Apr. 19, 1932 STATES ice STEAM PURIFIER Application filed I eeember 12, 1928, Serial No. 325,607, and in Germany April 24, 1928.

This invention relates to steam'purifiers and more particularly that type of purifier where the steam is directed through a nozzle, the impurities being diverted into one path while the steam escapes by another path.

The object of the invention is to provide a nozzle which will receive the wet and impure steam and which will separate the water and other impurities in the steam during the passage through the nozzle.

A further object is to provide a restricted circular opening for the wet, impure steam and bafiles to direct the steam through a tortuous path while at the same time directing the impurities through a straight path.

The invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a vertical section of the nozzle.

Fig. 2 is a section on line ABO of Fig. l.

The purifier comprises a casing A of any desired shape having a nozzle formed inside and integral therewith with a second nozzle carried directly below the first mentioned nozzle.

The wet and impure steam enters the ports (2)which are formed by the cover (3) and the upper wall l) of the steam nozzle (5) by way of the ring-shaped opening (1) from all sides. Whilst this happens, the steam is gradually deviated by 90, in consequence of which the large drops of water contained by the steam and as a rule, irregularly dis tributed among it, as well as the large kind of impurities are forced to move towards the central axis (66) of the steam nozzle and towards the conical point (7) of the cover. For the purpose of retaining these substances in this axial position so that they may be ejected as completely as possible, the point being forced towards the opposite side of the nozzle.

Through the tapering nozzle the impure steam, after leaving the ports (2) passes with increasing speed and thus reaches the narrowest part (9) of the cross section which is of considerable length in order to ensure that the admixtures-more particularly the large substances among them-are likewise moved along a high rate of speed.

The end of the steam nozzle projects freely into 'the'interior deviating and discharging space (10) of the steam purifier. If any connecting ribs were provided between the end of the nozzle and the wall of the steam puriher, they would cause the water to adhere to them which would mean that there would be a danger of their being forced to join the steam et during its discharge. The tapering configuration (11) of the lower end of the nozzle wall also favours the separation of the water from the steam. Moreover, in order to prevent the onesided deviation of the steam jet as it emerges from the nozzlewhich would also cause the particles already separated to rejoin itseveral perforated sheets (12) have been fitted to the passage through which the steam is discharged. 'The holes in them are of a smaller width than the eX- haust opening (13), so that the steam is forced to leave uniformly in all directions from the end of the nozzle.

The efifect produced by all these arrangements is that, when the steam jet proceeding from the nozzle is deviated in the direction of the arrows (14), all the particles of water carried by it and all other substances it contains are hurled, at a high rate of speed, into the combining nozzle (15). The latter consists of an upper part (16) which is of slightly greater width than the steam nozzle and whose width is about equal to its depth, and a lower part (1'?) which tapers in front and is provided with opening (18). Through the latter the water and the other foreign substances separated from the steam are conveyed into the delivery nozzle (19), where their considerable kinetic energy is converted into pressure, so that their discharge is ensured even in the a comparatively narrow event of there being a considerable amount of pressure above atmospheric in the outer space (20) as compared with the inner portion of the combining nozzle.

What I claim, is the following:

1. A steam purifier comprising a casing formed with a chamber, a nozzle depending into the chamber, the upper portion of the nozzle flaring outwardly, a cover provided over and spaced from the upper flared portion of said nozzle to provide an inlet port, said cover being correspondingly flared, the inverted apex of the flared covering extending downwardly into the upper end of the nozzle.

2. A steam purifier comprising a casing formed with a chamber, a nozzle depending into the chamber, the upper portion of the nozzle flaring outwardly, a cover provided over and spaced from the upper flared portion of said nozzle to provide an inlet port, acentral conical portion depending from said cover, said portion extending into the upper part of said nozzle and terminating below the inlet opening, baffles provided in said inlet opening which with the depending conical portion direct the inflowing steam into the nozzle, a second nozzle arranged in vertical alignment with the first having a restricted opening, thereby forcing the pure steam around the first nozzle into the chamber, and a screen in said chamber to uniformly direct the steam.

In testimony whereof he ailixes his signature.
